How it is scored
12 checks worth 54 points, grouped by the artifact each one reads. A facet's sub-score is its awarded points normalized against the points that were actually applicable to that provider — a check needing an artifact the provider does not publish at all is N/A, and leaves both sides of the fraction.
apis.yml ·
apis_yml| Check | Rule | Points |
|---|---|---|
| Publishes an apis.yml indexThe provider maintains a real APIs.json index rather than being catalogued from the outside. The single highest-value discoverability signal: it is the difference between a provider describing itself and being described. | source_filename == "apis.yml" | 10 |
| Substantive descriptionAt least 200 characters of description. Enough for a human or an agent to decide whether the API is relevant without opening the site. | len(description) >= 200 | 5 |
| Tagged for discoveryFive or more tags. Tags are how the API surfaces in topical search and how it gets placed into industries and areas rather than sitting unclassified. | len(tags) >= 5 | 5 |
| Provider imageA logo or image is referenced, so the provider renders as a recognizable card in search results and listings instead of a bare line of text. | image is set | 2 |
| Named maintainerA contactable maintainer email. Establishes that someone owns the index and gives consumers a route to reach them. | maintainers[0].email is set | 3 |
| Created and modified datesBoth timestamps present as ISO dates, so freshness is machine-readable and a consumer can tell a maintained index from an abandoned one. | created and modified both ISO dates | 2 |
| Indexes three or more APIsThe index covers a real surface rather than a single endpoint — evidence the provider is cataloguing their whole platform. | api_count >= 3 | 3 |
| Human URL on every APIEach indexed API points at documentation a person can read. Without it, an entry is a name with nowhere to go. | every api has humanURL | 5 |
| Base URL on every APIEach indexed API declares a real, callable base URL. A localhost base URL fails this check — it signals a spec that was published without ever being pointed at production. | every api has baseURL and no baseURL contains "localhost" | 5 |
| Serves a .well-known surfaceThe provider serves machine entrypoints at RFC 8615 well-known paths — an api-catalog linkset (RFC 9727), a security.txt, an OAuth protected-resource document. This is the address an agent tries FIRST, before it has read anything, and it is the discoverability signal a marketing site cannot fake. | well-known/ carries an api-catalog, security.txt, a protected-resource doc, or an AAuth resource doc | 6 |
| Publishes llms.txtAn llms.txt — the provider stating, in a machine-readable file at a conventional path, what a language model should read to understand the product. Young, unratified, and adopted by 6,012 providers in this catalog, which makes it the fastest-moving machine-discoverability signal there is. | llms/ carries an llms.txt THE PROVIDER wrote, or a declared LLMsTxt pointer | 4 |
| Self-hosts the APIs.json indexThe provider serves its own APIs.json index from its own domain rather than being catalogued from the outside. `apis_yml_present` above rewards the index existing; this rewards the provider OWNING it — the difference between describing yourself and being described. | apis.yml url points at a host the provider controls, not the catalog | 4 |
